This thesis contains a description of the Lund-Potsdam-Jena Dynamic Global Vegetation Model (LPJ-DGVM) and its application to infer the role of vegetation dynamics on atmospheric CO2 content at different time-scales. The model combines vegetation dynamics and biogeochemistry in a modular framework. Individual modules describe ecosystems processes, including vegetation resource competition and prod

In many natural ecosystems, predation is well recognized as a strong evolutionary force, and predator-mediated selection has been demonstrated to induce changes in prey morphology, life history and behaviour. In my thesis, I have focused on behavioural responses in aquatic prey under the risk of predation. I have used two different species of prey, the guppy (Poecilia reticulata) from high and low

Popular Abstract in Swedish Materien strävar efter största möjliga oordning (entropi). Det krävs ett aktivt ingripande (energitillskott) för att ordna och separera saker. Har man väl hällt salt i teet är det svårt att ta bort, och byta ut det mot socker. Vid framställningen av olika ämnen får man ofta ut en blandning som även innehåller sådant man inte vill ha, och måste hitta sätt att skilja dem The purification of proteins from raw materials like fermentation broth and other biological sources usually involves several purification steps and is rather time consuming and expensive. This is a major concern in the production of many important protein products e.g. pharmaceuticals such as insulin and blood coagulation factors. One way to speed up the isolation of protein from particle-contai

Dieser Beitrag versteht sich als Kritik der mit dem Indizienparadigma verbundenen archäologischen Metapher des Spurenlesens. Spuren können, sobald sie als solche gesichert sind, keineswegs die Vergangenheit quasi von selbst zum Sprechen bringen, indem sie als historische Indizien Zugang zum ‚Kern der Dinge‘ erlauben. Stattdessen bedarf es eines kreativen Interpretierens, um Spuren erst bedeutungsv

Electrochemical reactions at the anode triple phase boundary (TPB) proceed on the basis of the fuel concentration, which depends on transport processes within the porous anode and the heterogeneous reforming chemistry. Microscale modeling is needed to describe these interactions with an acceptable accuracy. The aim of this article is to investigate if it is possible to use a multiscale approach to

Significant saving potential is believed to exist in all economic activities of the private sector of MENA countries. However this potential is hardly explored in systematic ways. Particularly in the context of a country like Saudi Arabia, where the cost of water production is among the highest in the world, the incentives to examine this potential should be high. In 2007, a group of private secto

Popular Abstract in Swedish Multikonjugerad Adaptiv Optik för Astronomiska Teleskop 1. Atmosfärisk turbulens Allt sedan man på 1600-talet började bruka optiska instrument inom astronomin, för att understödja det mänskliga ögat då man beskådade stjärnhimlen, har astronomer strävat efter att bygga allt större och bättre teleskop för att kunna se längre ut i rymden och skönja allt ljussvagare objekt.This work analyses several aspects of multi-conjugate adaptive optics (MCAO) for astronomy. The research ranges from fundamental and technical studies for present-day MCAO projects, to feasibility studies of high-order MCAO instruments for the extremely large telescopes (ELTs) of the future. The first part is an introductory exposition on atmospheric turbulence, adaptive optics (AO) and MCAO, esta

In order to study nanoparticles in an efficient way, new characterization methods has to be developed in parallel with the efforts to develop new preparation methods. One such characterization method is cryo-transmission electron microscopy (cryo-TEM) which gives the possibility to image nanoparticles as they are in solution. The particle-containing solution is plunge-frozen, creating a thin froze
